If a function is decreasing over a closed interval, the right endpoints will be used for the lower sum and the left endpoints the upper sum.example: Finding Lower and Upper Sums Find a lower sum for f(x)=10−x2f(x)=10−x2 on [1,2][1,2]; use n=4n=4 subintervals. Show ...

The Riemann sum allows us to approximate the definite integral of a function. Learn about the left and right Riemann sums here!
The left endpoints Riemann sum is L n = ∆x f(x 0 ) +f(x 1 ) +· ·· +f(x n−1 ) = ∆x n i=1 f a +(i−1)∆x Step 5. The right endpoints Riemann sum is R n = ∆x f(x 1 ) +f(x 2 ) +· ·· +f(x n ) = ∆x n i=1 f a +i∆x ...
